Implementation of routine operation for production of standard air for delivery to isotope labs requiring high precision calibrationImplementation of

The new Standard Reference Material (SRM) for CO2 isotopes has been generated, distributed and tested by user laboratories. This is a significant advance in isotope meteorology for atmospheric CO2 studies because the new SRM is an immediate link of the CO2-in-air scale to the international calcite material standard VPDB. It has no equivalent elsewhere in other laboratories. Summarized below are the main steps needed to accomplish associated.

Routine operation for production of SRM for delivery to isotope laboratories has been achieved. A large number of preparations have been made using various carbonate materials as well as established CO2 gas standards.
